Provided is an adhesive film for a metal terminal that exhibits high adhesion strength to a metal terminal when it is heated and pressurized a plurality of times before being adhered to the metal terminal. An adhesive film for metal terminals, which is interposed between a metal terminal electrically connected to an electrode of a power storage device element and an exterior material for a power storage device that seals the power storage device element. The adhesive film for metal terminals is allowed to stand for 12 seconds in a heating and pressurizing environment having a temperature of 180 ° C. and a surface pressure of 0.0067 MPa, and further standing for 1 hour in an environment having a temperature of 25 ° C., and then having a temperature of 25 ° C. An adhesive film for metal terminals having a tensile elastic modulus A measured in an environment of 490 MPa or more. |
